When it comes to technology, most people are content to just use it without wondering how it does what it does. Like a digital camcorder, millions of people use them without a second thought, but haven’t you ever wondered how the camcorder captures images? While the tech itself might be complicated, the answer is relatively simple.

How does the camcorder record my videos?

All digital camcorders use a special image sensor to record images. The camcorder lens focuses light on the image sensor, which is a charge-coupled device (or CCD). The CCD is packed with hundreds of thousands of special light-sensitive diodes, called photosites, that can detect how strong light is. When the lens focuses an image on the camcorder’s CCD, each individual photosite measures how strong the light is in its particular part of the sensor and converts that measurement to an electrical charge; the stronger the light, the stronger the electrical charge. The camcorder then records the different levels of electricity for each part of the image.

So how does the CCD capture color images?

The process is the same: the photosites record the intensity of light, but only in a specific color. The camcorder CCD records the various intensities of blue, green and red light in the picture, then combines the three colors into a full-color image. Most camcorders use a color filter with repeating patterns of cells in the three colors. The most expensive camcorders, however, will split the light from the lens in three directions and use three separate colored CCDs to record the image.

How does my TV or computer display the image?

When the camcorder CCD records the intensity of light for the various colors, the information is stored digitally. Your computer and your TV (if you have a digital TV or digital tuner) can simply take that information and reverse the process, increasing intensity of light in specific areas of the image depending on the intensity of the electrical charge. If your TV is not digital, the information must be converted to an analog signal. Ultimately the end result is the same, and the wonderful camcorder CCD technology made it all possible.
